Expand description

Open (or join) the shared root for an FS_SYNC_SINGLE sync of path (a canonical FILE path from validate_single_root). The native watch arms on the file’s PARENT directory, non-recursive — a watch on the file itself would follow its inode and go silent after a delete or a rename-over, exactly the transitions a single-file sync must deliver. recursive/cross_filesystem/ignores do not apply (nothing is enumerated — the client named the one file it wants), so every SINGLE sync of one file shares a single normalized key.
